ionic run browser --livereload not working

i found the solution on the github page

include a script in the package.json file

"browser": "ionic-app-scripts serve --sourceMap source-map --iscordovaserve --wwwDir platforms/browser/www/ --buildDir platforms/browser/www/build"

and run

npm run browser

When you run the command ionic cordova run browser --livereload you will see something like this in CLI:

[19:39:00]  dev server running: http://localhost:8100/ 

[INFO] Development server running
       Local: http://localhost:8100
       External: http://192.168.0.51:8100

Just open http://192.168.0.51:8100 or http://localhost:8100 and your live reload will work on that address. Your browser might have opened in http://localhost:8000 instead of 8100
